Short summary
The Cretaceous was punctuated by several episodes of accelerated global change, defined as Oceanic Anoxic Events (OAE), that reflect abrupt changes in global carbon cycling. In this progress report, we present a new drill core recovering an Aptian section spanning OAE1a in southern Spain. The Cau section is located in the easternmost part of the Prebetic Zone (Betic Cordillera). All the studies performed reveal that the Cau section represents an excellent site to further investigate OAE1a.
